Abstract The vertical extension of a general circulation model generally requires a modification of the model's highly parameterized radiation scheme in order to include approximately the absorption by lines with a Voigt profile. For the European Centre for Medium-Range Weather Forecasts radiation scheme, a modification of the Lorentz line width provides a practical solution for this problem. Thus, the domain of this wideband radiation scheme is extended from the surface up to the mesopause.
